40A cam switch, direction of rotation reversing switch L-0-P, in OB3 enclosure with yellow/red locking front ŁK40-3.8368\OB3ZC

Universal cam switch for demanding applications

This three-pole cam switch with a rated current of 40A is a reliable solution for controlling electrical circuits. Designed for both industrial installations and professional use, it provides safe and efficient change of motor rotation direction or circuit switching. The robust construction and high IP65 protection rating guarantee long-lasting and trouble-free operation even in harsh environmental conditions.

Construction and functionality

The switch is housed in a durable OB3 enclosure with a lockable front, available in yellow and red – which facilitates identification and control of the device status. The L-0-P switching mechanism allows you to choose between two directions of rotation, power off (position 0), and standard operation. Screw connection of the main contacts ensures a secure and durable connection of wires with a cross-section from 4 to 10 mm². The device is complete, ready for mounting and does not require additional elements.

User parameters and safety

The switch is characterized by high technical parameters, such as a rated power of 20 kW for AC-3 at 400V and a continuous rated current of 40A. It provides effective protection against overload and short circuit – like most circuit breakers in this class. The construction meets stringent safety standards, confirmed by a high degree of protection IP65, which protects against access to live parts and the influence of dust and water. Additionally, the device is resistant to vibrations and mechanical shocks, which increases its reliability in demanding applications. Designed to operate in a wide temperature range – from -40°C to +70°C – making it an ideal solution for both indoor and outdoor applications.
